'FECII'ICATION forming parl; of Letters Patent No. 346,193, dated `Tuly 27, lzi' Serial No. liltlfill` (No inolhli To @ZZ whom z' 11mg concern.-

Be it known that I, EDWARD R. CoNnLiN, a citizen of the United States, residing at 1Nauseen, in the county of Fulton and State of Ohio, have invented certain new and useful Improvements in \Vheel-Cultivators; and l do declare the following' to be a full, clear, and cx-- exact description ot' the invention, sueltas will enable others skilled in theart to which itappertains to malte and use the same, reference being' had to the accompanyingdrawings, and to the letters and tig-ares ot rct'erence marked thcreon,whieh form a part of this specification.

My invention relates to that class of culti.- vators which have the plow or cultiwdorhcams pivotally connected at their front ends to a draft-trame mounted on an arched axle, the drat'tl'rame and plow-beams being,l adjustably connected hy standards pivotally connected at their lower drat't ends with the plowbeams and with the d rait-frame by rods or links.

The object ot' my invention is to simplify and improve the Construction of this class ot' implements, to devise a construction whereby the cultivatordieams may he raised orlowcred simultaneously with the adjustment of the draft-trame, and the eultivatorheams be adj listed independent ofthe drat'tffranie.

lt consists in the novel features more fully hereinafter set forth, claimed, and shown in the accompanying drawings, in which- Figure l is a perspective view, parts broken away, of a cultivator otLmy construction embodying;l my improvements. liig'. 2 is an enlarged detail perspective view ot' the means connecting the lower ends ot' the staiulardrods with the axle.

The cnltivator or plow beamsA are pivotally connected with the draft-trame Yli hy curved draw-bars tl. Standards l), supporting the rear ends ol' the beams, are connected at their upper ends with the arched part E ot the axle lil by a stainlard-rod, F, bar (i, and connection ll, at their lower ends with the beam by loops or stirrups l. The standardrod F may comprise two parts, as shown, and a bar, (l, may be provided for the lower end of each part. These bars may be independent of each other orconnectcd together, as desired. The lower end or ends of the stand ardbar F are pivotally connected with the rear end ot the har G, which in turn is rigidly connected` with the upper end ot" the curved conncetionll', the lower endotl which iS rigidly secu red or clam ped to the arched pa rt ot'theaxle by a elip` Il. 'lhe drat't-l'ramc is extended hcyond its pivotal connection with the arched part ot' the axle and supports the drivel-s seat l. The lower part or spindle ot the axle lt] is adjnstahly connected with the lower end ot' a lever, J', pivoted on the dral't-l'rame, preterahly to the rear ol' the arch or raised portion lil, h v a link, l. lialehj and segment .V hold the lever in an adjusted position. ly operatine,` the lever l'orw-.ud or baelnvard the draft frame is correspondingly moved relative to the lower part ot' the axle, so that the seat is brought nearer to or farther from a line passing.,r vertically through said lower part ot'the axle. `lly reason el' the rigid connection ot' the hars tt with the raised part or areh ot the axle,and the rotation olthe latter relative to the frame, said hars are correspondiugly moved with the inovementotthe dral'tvl'ranie; but the stainlard-rods F, being pivotally conA neeted with the bars, are not in the least at'- t'eeted by their movement, and, as one ot' the Vita] points olmy invention is to move the standard rods simnltaneousl)Y wilh the adjust ment ot' the draltftrame, the following' nieans have been devised to canse a rie-id connection between the hars and rods at the dumm movement ot' the,` l`rame,to throw the rods t'orward and elevate the enltivalorheams. 4Levers ii, having their rear ends, curved upward and bearing upon the rear sides ofthe stainlard-bzus on their parts, and having their forward or front ends provided with slotted segments 1.1, are piveted to therear ends of the bars G, preferably on the same holt which connects the rods and bars together. A bolt or pin, (i, passing through the slotted segment into the har,servcs to hold the sanimwhifn adjusted relative to the standard-rods, and bars (l, whereby the throw of the standards may be regulated and the amount ol' elevation orvadA justmcnt ot the beams be governed.

In practice, the drivers seat may be adiust ed relative to the axleaecording to the weight ofthe driver. The lighter-thc weight the great er must he the leverage to ctleet a balance for the frame, andt he heavier the weight lhelcss the leveragez lhe leverage is the distance between vertical planes passing through the IVO driverfs seat and the lower parts or spindle of the axle. XVhen the planes coineide,the leverage is practically nothing, and the drivel-s seat is directly in line with and above the lower part or spindle of the axle. rlhis le vcrage is adjusted by the lever J and link c, and simultaneously therewith the bals G and levers K are moved, carrying with them the standard-rods F and standards I), which eil'ect a corresponding adjustment of the beams. The amount of-.nljustment ofthe beams isgoverned by the position ot' the lever K. If it be desired to raise the beams independent of the levers 'K and the movement of the bar G, it may be done by simply moving the rods F in the usual manner, as will be readily appreelated. Again, when the draft-frame is adjusted to a txed position, in order that a peri'ect equilibrium muy be had, it is necessary to adjust the beams to a certain elevation and hold them there, and the rods F are moved till the required adjustment is etected, when, by adjusting thelevers l( till their ends bear against and support the rods, the desired rcsult will be obtained.

The connection 1I may be rigid, it desired; but in practice the bestrcsults are had it" it be ot' elastic or spring material.

The lever l( maybe a fixture and its curved end a permanent stop in case the machine is not to be adj usted for carrying varyi ng weigh t s.

Having thus described my invention, what I claim,and desire to secure by Letters Patent, 1s-

1. In a wheel-cnltivator, the combination of the beam, the standard l), the standard-rod F, a bar,(l, and a stop, as li, bearing against the standard-rod and forminga support therefor, substantially as and for the purpose set forth.

2. ln a wheel-cultivator, the combination, with the beam, standard D, and standard-rod F, of a spring-support, ll, for bodily sustaining the slamlard-rod, substantially as shown and described.

3. In awheelcultivater, the combination of the beam, the standard Il, standard-rod F, a bar, (l, a revolnble support, ll', and a connection, ll, between the support and bar, substantially as described, and i'or the purposes specified.

4. In a wheel cultivalor, the combination of the beam-standard D, standard-rod F, bar G, lever K, pivoted thereto,and having a curved end bearing against and forming a support for the standardrod, and a springsupport, II, for the short bar, substantially as shown and described.

5. In a cultivator, the combination of the beam. the standard D, the standardrod F, a bar, G, and a pivoted lever, K, having one end bearing against and forming a stop for the standardrod and its other end vertically adjustable, whereby the elevation of the beam may be regulated, substantially as described.

(i. The combination ofthe beam, draft-frame, arched axle supporting the draft-frame on its arch, a bar, G, at a distance above the axle, a connection, H, securing it to the arch ot' the axle, a lever, K, having a curved end pivoted on the bar, a standard-rod, F, pivoted to the bar Gand resting on the curved end of the lever, a standard, D, connecting' the standard rod with the rear end ot' the beam, and a lever under the control ofthe driver forshitting the position ofthe supportiiig-wheels and simultaneously' effecting vertical adjustment of the beam, substantially as and for the purposes set forth.

7. In an agrieultu ral implement ot the hercindescribed type, the combination, with a support and the standard-rod pivotally connected therewith, of an adjusting device directly interposed between the support and standard-rod for adjusting the inclination of' the latter, substantially as and for the purposes described.

8. The combination of the draft-frame, the axle, beam, a bar, G, located above the axle, curved spring-connection uniting` the bar and axle, a lever pivoted on the bar and having one end curved and its other vertically adjustable, a standard-rod pivolally connected with the bar and resting on the curved end ot' the lever, and a standard having a stirrnp embracing the beam, substantially as shown, and for the purpose set forth.

In testimony whereof I al'tix my signature in presence ot' two witnesses.
